Could be a few things.

It could be the resolution settings.
It could be that your monitor isn't connecting to your computer. In this case you would have to get a card for the monitor to plug into.
It also could be that it's not supported by the OS.

Look for bad caps as shown in my pictures, common problem in all brands of LCD monitors.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

There are two places to look for the problems, the backlight inverter board and the power supply, look for burnt parts, bad capacitors, etc.

ViewSonic VA912b monitor fading out during boot


It is probably the power supply, or the inverters.

Similar problem with solution, though it requires you to know something about electronics.
